My invention relates to radiators for hot water or steam heating, of the type in which the radiating surface of each elementis con-` stitutedby a plurality of tubes, usually vertical, which are connected together at the top and bottom by main chambers whereby all the elements are enabled to communica-te. j `According to this invention, the walls of the elements arevery thin,`or below l millimetre, as may for example be obtained by an electrolytic deposit upon a core of destructible nature. In order to obtain the requisite strengthkin spite of this small thickness, the invention consists in giving to the tubes a circular section of small diameter, for instance less than lone centimetro, and in connecting said tubes with the main chambers of circular shape.I The ends of the tubes are formed as elbows and are joined to said 'chambers in a substantially perpendicular direction, and in this case the said elements can withstanda considerable internal pressure. Furthermore, in order that said elements may be assembled together by clamping without danger of breakage, the invention also consists in providing strong cross-bracing parts in said main chambers, and after the elements are juxtaposed, said parts will .support theneces'sary pressure which is applied parallel to the axis of the chambers. The widthof these latter corresponds as a rule to the diameter of the tubes, and the required spacing vof the elements is obtained by the insertion of heavy rings between the corresponding chambers so that the assembling pressure shall be brought to bear upon the whole set of rings and bracesy which are juxtaposed.

Inthis manner it willbe feasible to construct radiators which for al given heating surface will have a much lighter weightand less size than for the known radiators.

forml of construction of radiator according to this Ainvention is shown in the accompanying 'drawing by way of example.

Fig. 1 is a front elevation, .partly in section.'

Fig 2 is a side elevation, partly in section. n

Fig. 3 is a plan view, partlyinsection.

Figs. 4 `andi are perspectiveviews of an apertured socket and an inserted ring;

l indicates a set of tubes of'small diameter and thin walls whose ends are bent at an sleeve of suicient thickness provided with a plurality of apertures 5I connecting the interior of the .sleeve with the annular part of i the surrounding chamber. The walls :ofthe latter are assembled in a tight manner with the periphery of thesleeve 4 and are prefvq erably curved outwardly so as to form with the latter a collar of lgreater'or.lesslength 6.

In the preferred form of construction,"'the said radiator element is lobtained by 4casting in an easily fusible alloyA a core having the exact shape ofthe inner space to 'be' formed in the finished element, and by. depositing av layer of copper of suitable thickness upon the whole surface of said core, the, latter then being eliminated by melting. By this` process which 'has already been employed for various purposes in the industries, the tubes andthe circular chambers are formed inay single piece `in a .simple and inexpensive manner;7 and withr th-efm-aximum tightness and strength.v i I B fore placing the coating uponsaid core,` or even at the time ofvcasting the saine, .insertion/can be made not only of the sockets 4 but'also of small copperrods 'vfor brac.

ing the ohambers2, thereby. providing'A the most intimate connection betweensaid members` and the deposit v,forming the walls of` the element.` A number of likejuxtaposed elements are preferably assembled yby inserting between the same the ringsA 8 yfor eX- ample of. cast iron,` steel or the like which are properly iittedupon `the Vends of/the sockets i andthe collars 6. r

vThese latter a-repreferab'ly provided on their inner wall with a circularrib 9 which limitsthe 'tting upon the sockets 4. LThe thickness of the rings 8 in the axial sense corresponds to thedesiredspa'cing of the said elements. When the` elements, are asf sembled, said "rings will bear upon the i braced fiat walls of the chambers 2, so that the whole device may withstand strong pressures exerted on the axis of the chambers, as well as the internal pressure.

All the elements are placed in communication by the sleeves 4 by meansv of the apertures 5 of the latter. The number of the said elements will obviously vary according to the desired size of the radiator. The sockets of the elements situated at theY endof the series may be screwthreaded or provided-with flanges or otherwisedisposed for coupling the inlet and outlet piping or suitable plugs, or they may be connected with elements of any other construction and especially with cast iron radiator elements, which willl in turn be connected with the piping'and can be rigidly connected together so as to 'form a device wherein the elements 1^ with lthin walls are not exposed to damage.

' Obviously, the said arrangement for as sembling the elements which is given by way of example can be varied without departing from the principle of the invention, the same however being considered as the mostadvantageous.
